STOVE OR HEATER.

SPECIFICATION forming part of Letters Patent No. 314,205, dated March 17. 1885. Application filed December 4, 1883. (No model.)

To all whom it may concern:

Be it known that I, THOMAS J. Tenw, of Kirksville, in the county of Adair and State of Missouri, have invented a new and .useful Improvement in Stoves and Heaters, of which the following is a full, clear, and exact description.

My invention consists of an improved contrivance for making the top of a stove or heater of a deeply-corrugated plate of thin metal, and causing the heat to pass along the same to provide much larger radiating-surface, and consequently a more economical stove than has yet been made.

My invention also consists in providing a deflector-plate beneath the corrugated top, in connecting the indentations in the top plate, and in an outside hood, as hereinafter fully described and claimed. 7

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional elevation of my improved stove, and Fig. 2 is also a sectional elevation, the two sections being taken in planes crossing each other at right angles.

I make the top of the stove to consist of a deeply-corrugated thin metal plate, a, preferably sheet-iron, to form high inside spaces, 7), in which the heat may rise between the deep outside spaces, 0, in which the air may have contact with a large heating-surface. In practice I propose to make these corrugations about two feet deep for a heater of ordinary size for large rooms. I also propose to make one or more pipe'connections, Z, across the airspaces 0, and through the plate a, connecting the heating-spaces b, and to provide said connections with dampers 1', to allow the draft to pass through them when it may be desired, said pipes discharging at or near the smokepipe 9, and in some cases will apply a hood,

'm, of sheet metal, above the corrugated top of the stove, to conduct the heated air from the said top downward and discharge it near the floor.

The plates a'and m may be connected with the rest of the stove in any approved way;

but a simple way which I prefer consists of making two cast -iron end plates, d, with grooves e of suitable form in one side of each plate to receive the ends of the longitudinal plates, the said longitudinal plates and end plates being fastened in any approved way to prevent the end plates from separating from the plate a, as angle-plates attached to both, or rods may extend through the end plates from one to the other.

The plate a may have a curved section, a, extending under it from end to end to form the sides and bottom of the fire-box, or said fire-box may be constructed in any other approved way.

The bottom may be used, as shown in the drawings, for burning wood, or it may have a fire-grate to burn coal, if desired, and over the fire-bed I propose to arrange a heavy plate,

f, connected to the side of the fire-box, from which the draft escapes by the smoke-pipe g, and extending nearly to the other side, but leaving a suitable passage, h, at the other side to cause the heated currents to traverse the whole length of the corrugated plate. I

The fueldoor k may be located in one of the end plates, and the door Z, for removing the ashes, in the other plate; or both may be ar ranged in one plate, as preferred.

I propose to use this improved heater either as a generator of heat by means of a fire within it, or up a heating-dome to be connected with the pipe from another heater, and in some cases may cover the top of the hood in with some nonheat-conducting material.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a stove and heater having the corrugated top plate, a, the said top plate having the lower curved section, a", connecting the ends of the same, and forming the sides and bottom of the fire-box, and the deflectingplate f, arranged under the corrugated part of the plate a, substantially as described.

2. The combination, in a stove and heater, of the corrugated top plate, a, having the smoke-pipe 9 connected at one end, and the deflecting-plate said plate causing the heat-- currents to pass 011 to the corrugated plate op- 5. In a stove and heater, the combination,

posite the smoke-pipe and to traverse the with the plates (2, having grooves e, of the corwhole length of said corrugated plate, subrugated top plate, a, the bottom plate, a, prostantially as described. vided with the deflector-plate], and the hood I 5 5 3. The combination of pipe connections Z I m, substantially as described.

with the corrugated top plate, a, substantially l as described.

4. The combination, with a stove and heater having the corrugated top plate, a, and con- Vitnesses: 1o nectingpipes Z, of the defiector-platcf, sub- L. P. ROBERTS,
